Macro Strategy - The chemical sector has seen continuous catalysts on both supply and demand sides since 2024, with the current "anti-involution" trend enhancing the market outlook, driven by a favorable fundamental environment and potential valuation uplift from emerging industries [1][23] - More than half of the existing convertible bonds in the chemical sector are issued at the peak of the cycle, currently entering or about to enter the redemption period, coinciding with an upward cycle, leading to more proactive debt conversion measures [1][23] - The majority of chemical convertible bonds are small-cap, which, combined with their near-term characteristics, amplifies the asymmetry of returns [1][23] Currency Exchange Rate - The RMB central parity has shown a gradual appreciation trend, with the exchange rate expected to challenge the 7.15 range again, and the spot exchange rate may drop to the 7.10-7.15 range in August [1][25] - The recent strengthening of the RMB is supported by optimistic expectations from US-China trade negotiations and a robust domestic stock market [1][25] Anti-Involution Policy - The "anti-involution" price governance aims to address three main objectives: short-term regulation of price wars, medium-term capacity reduction to promote supply-demand balance, and long-term price recovery, particularly in PPI [2][26] - The previous supply-side reforms led to a 10-month recovery in PPI, and under neutral assumptions, a similar recovery may take 11-12 months, potentially reaching around 1.9% by September next year [2][26] Industry Rotation - The market is expected to remain optimistic in the third quarter, with a focus on sectors that align with upcoming policies and key events, particularly those benefiting from the "anti-involution" strategy [3][5] - Suggested sectors for investment include those with potential short-term demand improvements, such as photovoltaic, coal, and chemical industries, as well as technology sectors with recent catalysts [5][3] Company-Specific Insights - Xidi Microelectronics is positioned as a leading player in the analog chip sector, with a projected revenue growth of 32.10% year-on-year for the first three quarters of 2024, driven by significant contributions from its audio coil motor driver chip product line [11][12] - Minshida reported a 27.91% year-on-year revenue increase in its 2025 mid-year report, with expectations for continued growth in the transformer market driven by demand from sectors like new energy vehicles and wind power [13] - Gaomei's second-quarter performance is expected to turn profitable due to supply-side optimization driven by the "anti-involution" policy, with N-type silicon wafer prices rising to 1.1 yuan per piece [14][15]
